But for several years now, scientists and government agencies in Hawaii have been eyeing the technology for a much different purpose: saving what’s left of the Aloha State’s endangered birds from extinction.
“We’ve got this amazing treasure, birds found nowhere else in the world,” Dr. Lisa Crampton, project leader of the Kauai Forest Bird Recovery Project, told The Huffington Post. “And it’s our responsibility to take care of them.”
Crampton said mosquito-borne diseases, specifically avian malaria, are among the biggest threats facing Hawaii’s isolated bird species, and “we’d be remiss to at least not consider” all possible conservation measures, including genetic engineering.
Today, he’s leading a group of researchers at the Pirbright Institute to develop prototype genetic strains of Culex quinquefasciatus, the mosquito species plaguing Hawaiian birds.
Alphey told HuffPost that his discussions with experts in Hawaii over the last several years have only increased his confidence that gene-altered mosquitoes would work.
“GM mosquitoes could provide a powerful control tool which, if used in a properly funded program with support from the public and relevant agencies, could — in my view — greatly mitigate the problem and yes, in short, save these rare birds,” he said in an email.
Any chance of the innovative method being used in Hawaii, however, likely hinges on what the Food and Drug Administration decides in Florida, where it is assessing the potential impacts of allowing Oxitec to begin field trials.
Brent Lawrence, a spokesman for the U.S. Fish and Wildlife Service, told HuffPost in an email that the agency and its partners are “evaluating a wide range of control techniques” to protect native Hawaiian birds and ecosystems, and are “aware of the evolving technology on genetically modified mosquitoes.”
Any discussions prior to FDA approval in Florida, however, are “purely speculative and are very informal ‘what ifs,’” he said.
And then there’s the challenge of getting Hawaii on board — a “difficult sell,” according to Eben Paxton, an avian ecologist with the U.S. Geological Survey in Hawaii.
As Crampton notes, the last thing Hawaii needs is another situation like the mongooses, which were intentionally introduced in Hawaii to control rats. Unfortunately, rats are nocturnal, so the mongooses spent their days preying not on their intended target, but on native bird populations.
If executed properly, however, Paxton says genetically engineered mosquitos could be the best — and possibly the only — way forward for Hawaii’s rarest birds.
“This is an action to save these native species of birds,” he told HuffPost. “And without action there’s a reality that we might lose many of these species in the future.”
